Be it knownl that I, JOSEPH TRIGKEL, ay

citizen of e the United States, residing at Reading, in the county ofBerks and State of l Pennsylvania, vhave invented ,certain new. and

useful Improvements inPipe Vises,'of which the following is a specllicatlon.

This inventionrelates-to improvements'in pipe vises, and the object in the present invention is Lto' provideiapipe vise of com7 paratively simple construction, one in which varied sizes of pipe may be securely held, and one in which the pipe may be easily and rapidly released from engagement by when being gripped and held in position in the v ise, together with a iexible member,

preferably in the form of a link chain,V ,v adapted to partly surround lthe pipe, and

means for drawing this chain taut and securing it in tightened position.

The invention may be provided with means for securing it to a table, or, as shown in the drawings, with means for securing it to some suitable vertical post or upright.

The invention is more fully described in the following specification and clearly illustrated in the accompanying drawing, in which Y Figure 1 is a plan view of my device.V

Figure 2 is an end elevationalview thereof, partly in section.

Figure 3 is a sectional view, taken centrally through Figure 1, on the line 3.

The numeral 1 designates the base plate, and this is formed with means for securing it in position, preferably a split sleeve 2 provided' with a set screw 3, by means of which the device may be secured to an upright or post 4. j

The base plate is formed with upstanding portions 5, providing bearings for a pair of rolls 6 which are rotatably mounted therein.

These rolls are formed with annular serrations 7 'andl are arranged parallel with each other.V i Y Y Y t Y The rolls are smaller'indiarnete'rl attheir longitudinal centres than at eitherend, and Y the pipe to be secureduwill rest upon-,the

surfaces of the rolls.

The numeral `10 designates; a lerriblemem-;

ber, preferablyin the form cfa-flinkchain,

which; serves asthe medium :forv securely f holding the pipe againstthe serrated rolls. This chain is provided with the usual link pins 11 the ends of which project slightlyV from both sides of the links, and the under face of the base plate is provided with a pair of indentations 12, adapted to receive the projecting ends of one of the link pins.

The other end of the chain is provided with` a suitable tightening means, preferably in the form of a sleeve 15 and a screw 16, which sleeve is provided with an operating handle 17 whereby, the turning of the handle will tighten the chain and draw it tightly against the surfacefof the pipe, when the position across the rolls. Y

On the base plate, located between the rolls, I form a vertical post or support 20, the'upper end of which is about in horizontal alinement with the centre or lesser diameters of the rolls, so that, whenea pipe of relatively small diameter is to be. secured in latter is in upon the serrated roll surfaces.

This support will prevent the crushing of' the pipe when the chain is drawn taut.

Larger diameter pipe will not rest' upon thek postpwhen lying across the rolls, due to the larger diameter, but this support will not be 'required in other than 'pipe of relatively small diameters.

` Itis evidentA therefore, that to secure ,the`

pipe in the vise, it will be laid Vacross Vthe rolls, the free end of 'the' chain placedv over it, with the end hanging down across the'y base plate. One of the linkV pins is then placed.Vv in engagement with the indentations on theV under kface of the' plate, and theY handle 17 is turned until the chainis taut, thus securely holding the pipe in position in the vise; To release the pi e,`it is only necessary to turnV the handle 1 slightly in the opposite direction, which will permit the L disengagement of the link pins with the base plate, and permit the pipe to bewithdrawn.

as the vise, it will rest upon this post as well as Having thus fully described my invention, what I claim and desire to secure by Letters Patent is l. In a pipe vise, the combination of a base, a pair of parallel, annularly serrated rolls of varied diameter mounted on the base for rotation, a verticalpipe'supporting post located between the rolls, a chain for holding p the pipe in contact against the rolls, and means for drawing said chain taut and means for holding the chain in position when so drawn. t

2. In a device ofthe 'character and for the purpose described, the combination of a base plate provided with a plurality of vertical bearings and formed With an indentation on its under Side; a vpair of parallel,^annularly serrated rolls of varied diameter rotatably mounted on said bearings; a exible pipe gripping member having a'screw threaded portion at one end passing through the plate,

Von the rolls.

and a tightening device on said screw, said flexible member having a plurality of pro-y j ect-ions f adapted to engage the :indentations on lthe plate, and avertialfppef siippoting post located on'the plate, between the rolls at their smaller diameters.
